Cov hau kev ua kom huv ntawm cov ntoo flake graphite thiab lawv cov txiaj ntsig thiab qhov tsis zoo

Fig Kas graphiteYog siv dav hauv kev lag luam, tab sis qhov kev thov rau daim flake graphite sib txawv hauv kev lag luam sib txawv, yog li flake graphite xav tau cov txheej txheem sib txawv. Cov hauv qab no cov txiv hmab txiv ntoo graphite yuav piav qhia txog qhov ua kom huv siFig Kas graphitemuaj:

1. Hydrofluoric acid qauv.
Lub ntsiab zoo ntawm hydrofluoric acid txheej txheem yog qhov kev tawm tsam loj, muaj kev cuam tshuam ntau ntawm cov khoom lag luam graphite thiab kev siv hluav taws xob tsawg. Qhov tsis zoo yog tias hydrofluoric acid yog cov tshuaj lom thiab xeb, thiab nruj nruj kev tiv thaiv kev nyab xeeb. Ib qho ntxiv, cov dej khib nyiab tsim los ntawm hydrofluoric acid txuj ci yog heev tshuaj accic accic yog heev tshuaj lom thiab corrosive, thiab nws xav tau kev kho mob nruj ua ntej nws tuaj yeem tso tawm. Kev nqis peev hauv kev tiv thaiv ib puag ncig kuj tau txo qhov zoo ntawm cov nqi qis ntawm cov qauv siv roj hydrodlicic.
2, qhov yooj yim acid kuab qauv.
Cov pa roj carbon cov ntsiab lus ntawm cov qauv alkaline acid tuaj yeem ncav cuag ntau dua 99%, uas muaj cov khoom lag luam qis thiab muaj zog ua tau zoo. Ntxiv mus, nws muaj qhov zoo ntawm cov khoom siv niaj zaus thiab cov versatility muaj zog. Cov txheej txheem acid yog qhov feem ntau siv cov qauv hauv Suav teb. Nws qhov tsis zoo yog kev siv hluav taws xob loj, lub sijhawm ntev dhau los, cov kuab tshuaj poob qis loj thiab muaj kuab paug pov tseg.
3. Chlorination txoj kev.
Cov tshuaj kub uas tsis muaj qhov kub thiab txias thiab cov tshuaj chlorine tsawg ntawm chlorination roasting txoj kev heev txo cov nqi ntau lawmnpaimCov. Nyob rau tib lub sijhawm, cov ntsiab lus carbon ntawm cov khoom lag luam graphite cov khoom lag luam yog sib npaug ntawm cov qauv ntawm chlorination slour yog siab dua. Txawm li cas los xij, vim tias chlorine yog tshuaj lom thiab xeb, nws yuav tsum tau kho nruj me ntsis, thiab rau qee yam, nws txwv nws thiab daim ntawv thov.
4. Txuj ci kub siab.
Qhov loj tshaj plaws kom zoo dua ntawm txoj kev siab-kub-yog tias cov pa roj carbon ntawm cov khoom lag luam muaj siab heev, uas tuaj yeem ncav cuag saum 99.995%. Qhov tsis zoo yog tias cov cua sov kub yuav tsum tau tsim tshwj xeeb thiab ua tiav, cov cuab yeej siv kim, thiab muaj ntau txoj kev nqis peev thib ob. Tsis tas li ntawd, kev siv zog tau siv hluav taws xob yog qhov siab, thiab cov hluav taws xob siab nce cov nqi tsim khoom. Ntxiv mus, cov txheej txheem hnyav ua ke kuj ua rau daim ntawv thov tau ntawm cov qauv no tsis muaj tsawg. Tsuas yog nyob rau hauv lub teb chaws tiv thaiv, aerospace thiab lwm yam kev xav tau tshwj xeeb ntawm cov khoom noj huv ntawm cov khoom lag luam graphite, hom no tau txiav txim siab rau cov khoom lag luam me menpaim, thiab nws tsis tuaj yeem yog cov duab uas muaj nyob hauv kev lag luam.
